Chemistry
1 answer:
marishachu [46]3 years ago
5 0

when an optical telescope located on the ground is used to view the sky the image has to surpass through the earth's atmosphere which is polluted. so the resolution wont be clear. When viewed on a mountain top both optical and infrared telescopes would perform better as the air above the atmosphere is less depth and cleaner.

Find the mass of oxygen in grams produced by the decomposition of 100.0 g of CO2
SSSSS [86.1K]

The balanced chemical equation is :

2CO_2->2CO+O_2\\\\

Moles of CO_2 ,

n = \dfrac{100\ g}{44.01\ g/mol}\\\\n=2.27\ mol

Now, by given chemical equation , we can see 2 mole of CO_2 react with 1 mole of O_2.

So , 2.27 mole react with :

N=\dfrac{2.27}{2}\ mol\\\\N=1.135\ mol

Mass of oxygen is :

M = N \times 16\\\\M=1.135\times 16\ g\\\\M =18.16\ g

Therefore, mass of oxygen in grams produced is 18.16 g.

Hence, this is the required solution.
